It's the most important question in the multiverse: Which spaceship is the greatest? Which flies the fastest, has the best weaponry, and has the coolest design. Only you can decide: What is the greatest fictional spaceship in the entire multiverse?

Please include a picture or clip (or book cover) for your chosen spaceship. And please mention its name, and where it comes from. (Also, you can star other people's entries, to help bump them up.) Thanks!
